WooCommerce: Add to Cart Pre-defined Quantity Selectors

I seriously spent more than usual trying to write a decent title. Still, I’m not 100% sure I’ve explained it well – so here’s some more context.

The WooCommerce Single Product Page add to cart form features a quantity input and an add to cart button. Super simple. Customers can define a quantity and add the current product to the cart.

Now, let’s imagine you want to change this experience based on your business requirements, and instead of the quantity input and add to cart button you want to show 3 buttons: “Add 1 to the cart“, “Add 2 to the cart“, “Add 3 to the cart.

And if you can match this with a bulk quantity discount functionality, you can even change the messaging to e.g. “Add 1 to the cart“, “Add 2 to the cart and save $X“, “Add 3 to the cart and save $Y“…

So, let’s see how to hide the default add to cart form, and instead show buttons that allow the customer to add to cart a pre-defined product quantity (for simple products). As per this screenshot:

No more add to cart form – instead, we display pre-defined quantity select buttons, so that we force the customer to pick one of the 3. Works even better if you have bulk discounts!

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.
